just got this car and i dont know where to start.....

yea, also, you better be sure of two things. 1) make sure it was in her name, and she signed the title. 2) that if it was in the ex-husbands' name, that HE is the one who signed it.
cause if she signed it, and you go and put 10,000 into the car, you will in the end be out of all that you put into it. he can take the car from you, as he was the owner, and she forged his signature. you may think just cause you get the title in your name at dmv, that it is all good, but if he sees the car, and will know it is his, he can go to your house with a police officer, and legally take the car from you. then you have to take it up with the douche who sold it to you
